The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

The experiment was carried in INRA (Institut National de la Recherche Agronomique) at Theix, France. Two grasses (perennial ryegrass and tall fescue) were grown in sward boxes (0,13 m2) and submitted to three defoliation intervals (3,5, 7 and 14 days between two successive defoliation) and three defoliation intensities (160, 320 and 640 bites.m-2 at each defoliation). Four months after sowing, at defoliation date, sward boxes were offered to four individual dry ewes and removed after a given number of bites […]

A field trial was carried out to evaluate the effect of nitrogen (N) levels (0, 60, 120 e 180 kg/ha) and sowing methods (broadcast and .40, .80, and 1.20 m between rows) on dry matter yield (DMY), tiller densities and crude protein content, and minerals (P, K, Ca and Mg) of the material of post harvesting of the millet seed. A completely randomized block experimental design with the treatment in a split plot arrangement was used, with the sowing methods […]
